Guys  
Please check the following link.  
[http://www.notestips.com/flashchart1.html](http://www.notestips.com/flashchart1.html)

if you click on update chart, you will see the bars setting up as per the field value.

this guy who created the chart has given a maths equation to set the bar height according to field value.

duplicateMovieClip(“y”, bar, m);  
setProperty(bar, \_width, Number(Lenght)/Number(NoOfValues));  
setProperty(bar, \_x, Number(getProperty(XAxis, \_x))+Number((2_n-1)/2_(Number(getProperty(bar, \_width))+10)));  
setProperty(bar, \_height, (eval(“y” add n)/max)\*Hight);  
setProperty(bar, \_y, Number(getProperty(yAxis, \_y))-Number(getProperty(bar, \_height))/2);

Since i am not that familiar with actionscript, i am confused how he calculates the bar height.

he has taken the major source help from flash kit tutorial, dynamic flash chart.

I need a simple code to calculate the bar height.  
thanks for your help.
